Why do martial artists scream?

Some but not all martial artists will scream, and make other noises when fighting. Individual and teacher preferences influence these sounds. In some martial arts schools, each individual decides on the type of sound they will make.

A scream can contribute or take away from the power of a martial technique, depending on how the sound and technique are done. Some believe that it can also reduce injury, and reduce the risk that the yelling person will be knocked out if hit while yelling.

The principled coach or player might dismiss the importance of these things, and display their civility by refraining from yelling. The goal of a combatant should not be to be portray civility — the goal should be to awaken and manage one’s wild side.

Personality and individuality are important considerations. Some benefit from certain types of yelling, while others may not need to yell and still fight quite well. Sometimes, yelling will adversely affect the opponent, to the advantage of the person yelling. Sometimes, it won’t make a difference.

Those criticizing the use of yelling may be doing so because they do not understand why it matters, or they may not themselves benefit from yelling.

Proper yelling can help some fighters, while hindering their opponents. Stimulating your opponent’s senses with a properly timed yell can be an effective way to control or dull your opponent’s attention.
